It's ironic how you replaced "millionaires" in that quote since many engineers are now millionaires.
You don't go from worker to owner until you buy three properties to rent out or start your own business.
A mere millionaire is a lot less rich today b/c inflation (though probably still at least petit bourgeois.)
understood the theory isn't all about that. I reflect on work because I think so much of liberation can begin with freeing peoples time/regaining 'real' control of their time
